We are interested in the ecological processes that limit populations and contribute to the assembly of communities, and how land use impacts those processes.We use experimental manipulations of small streams and their riparian areas as our study system, and we have manipulated inputs, species composition, abiotic factors, physical structure, etc., to test hypotheses about these processes and how they contribute to biodiversity and ecosystem function.

Urban centres can be designed and managed to contribute to biodiversity conservation commitments. Topics include designing human-dominated landscapes to promote biodiversity, the tools required, assessing outcomes, and the benefits and negatives of nature in the city.
